Description
An account of the resource
The paper, starting with some preliminary considerations about the new mobile media ecology, in which today's children live, and with some data about the diffusion of mobile internet and smartphones among children, aims to focus on three main points. I first ponder the new opportunities and new risks arising for children from the diffusion of such technologies, and the related usage practices, looking at some preliminary empirical findings, coming from qualitative researches I conducted with some of my colleagues from OssCom (Giovanna Mascheroni and Maria Francesca Murru), about the domestication of smartphones, mobile social networking and location-based practices in the Italian youth context. Then, I explore the new challenges in parental mediation, starting from qualitative evidence gathered from Italian parents. I finish illustrating the contribution of the new European project Net Children Go Mobile towards filling the current knowledge gap regarding European children’s mobile internet and convergent mobile media use, risks and online safety. Investigación de la domesticación de la convergencia de los medios móviles e internet móvil por parte de niños y adolescentes: cuestiones previas y hallazgos empíricos sobre las oportunidades y riesgos Resumen A partir de algunas consideraciones preliminares sobre la nueva ecología de los medios móviles, en los que los niños de hoy viven, y con algunos datos sobre la difusión de Internet móvil y los teléfonos inteligentes, este documento tiene como objetivo centrarse en tres puntos principales. El primero, reflexionar sobre las nuevas oportunidades y nuevos riesgos para los niños con este tipo de tecnologías, y las prácticas de uso relacionados, mirando a algunos hallazgos empíricos preliminares, procedentes de investigaciones cualitativas que llevé a cabo con algunos de mis colegas de OssCom (Giovanna Mascheroni y Maria Francesca Murru), acerca de la domesticación de los teléfonos inteligentes, las redes sociales móviles y las prácticas basadas en la localización en el contexto de la juventud italiana. A continuación, se exploran los nuevos retos en la mediación de los padres, a partir de la evidencia cualitativa obtenida de padres italianos. Acabo de ilustrar la contribución del nuevo proyecto europeo Net niños Go Mobile, para llenar la brecha de conocimiento actual con respecto a los niños de Europa y el Internet móvil, el uso de medios móviles convergentes, los riesgos y la seguridad en línea. Palabras clave: Medios de comunicación móviles; Internet móvil; niños; oportunidades; riesgos.

Description
An account of the resource
With a growing world population and increasing demand for quality food in sufficient quantities, the aquaculture fits in this context as a producer of high quality animal protein with high productivity. The fish production in ponds has practiced for over five decades in Rio Grande do Sul state. The fish culture system commonly used is the carp only polyculture, which consists in culturing different carp species aiming to improve the performance of each one and, therefore, achieve high productivity. The carp polyculture has a low technological level and the production obtained is considered small moreover, the release of effluents in natural water bodies may cause an imbalance in the natural aquatic environment. Some studies have been performed adding the silver catfish to the traditional polyculture. Also, several studies were performed about economic viability, but with a single species, or consortium, as is the case of polyculture of shrimp and Nile tilapia. We tested the polyculture with partial substitution of 25, 50 and 75% of carps by silver catfish and Nile tilapia. We analyzed the economic viability of all substitution rates by obtaining the Net Present Value (NPV), Annual Value (AV), Internal Rate of Return (IRR) and Pay Back period. In conditions of uncertainty, we held on sensitivity analysis and evaluation through the Monte Carlo method. We concluded that substitution rate of 25% of carps by silver catfish and Nile tilapia has higher biomass production and better effluent quality. Regarding economic analysis, an investment in polyculture with vita useful 25 years is economically feasible for a fee Minimum Attractiveness (TMA) of 6.17%.

Description
An account of the resource
La inducción de agallas en plantas representa tanto modificaciones morfológicas como fisiológicas de órganos y tejidos vegetales causados por insectos endofagos. En el presente estudio, se realizó una revisión sobre los avances y desafíos para el estudio de este gremio de insectos, así como, la diversidad estimada de insectos agalladores y sus plantas hospederas en América Latina. Encontramos que la mayoría de estudios de insectos inductores de agallas durante el periodo 1950-2013 fueron realizados en Brasil y México, que en conjunto contribuyeron con cerca del 80% de la producción científica latino-americana. Para América Latina los insectos que inducen agallas pertenecen principalmente Diptera (500 spp.), Hemiptera (111 spp.), Hymenoptera (36 spp.), Coleoptera (20 spp.), Lepidoptera (19 spp.) y Thysanoptera (2 spp.). Fabaceae y Asteraceae son las principales familias hospederas de insectos que inducen agallas. Nosotros estimamos que deben existir cerca de 15,407 especies de insectos inductores de agallas en América Latina, siendo Brasil (5,540), México (4,286), Colombia (4,194) y Perú (3,090) que tendrían el mayor número esperado de especies agalladores.

Objetivos: Determinar el efecto de un programa de seguridad alimentaria (Redes Sostenibles para la Seguridad Alimentaria: REDESA) sobre la desnutrición crónica y sus factores causales en niños menores de tres años. Materiales y métodos: El resultado sobre la desnutrición se evaluó a través de la comparación de los porcentajes obtenidos en la evaluación inicial (2001) y en la evaluación final del Programa (2006). La desnutrición crónica fue definida como un índice de talla para la edad menor a -2DS, la referencia empleada fueron los patrones de la NCHS. El muestreo fue aleatorio multietápico; el tamaño muestral de la línea de base fueron 2643 niños y sus familias, para la evaluación final fueron 1597. Los factores causales se agruparon en: a) salud y alimentación, que comprendían las enfermedades diarreicas agudas (EDA), lactancia materna exclusiva (LME), alimentación durante y después de las enfermedades diarreicas; b) los económicos, que comprendía los ingresos familiares anuales y los gastos en alimentación. Resultados: La desnutrición crónica se redujo de 34,2% a 24,3%. Las EDA se redujeron de 35,0% a 16,4%, la LME se incrementó de 25,0% a 72,2%, la alimentación durante y después de las EDA se incrementó desde 3,3% a 45,0% y de 15,0% a 77,0% respectivamente, en todos los casos las diferencias fueron estadísticamente significativas (p

Description
An account of the resource
ABSTRACT Objective: To identify the role of the obesogenic environment and parental lifestyles in infant feeding behavior. Data sources: The searches were performed in PubMed, Medline, Cochrane, Lilacs and Scielo databases, in Portuguese, English and Spanish. The descriptors used were found in the Medical Subject Headings and in the Descriptors in Health Sciences being these: Comportamento alimentar/Feeding Behavior/ Conducta Alimentaria; Crianças/Child/ Niño; Relações familiares/Family Relations/Relaciones Familiares; e Ecologia/ Ecology/ Ecología. These were combined by the Boolean operator AND. Data synthesis: Researchers consider that parents (orprimary caregivers) are responsible, in part, for the unhealthy eating behavior presented by children, and for them to change it is necessary to change the behavior of the family, ensuring the correct choice of food and the practice of physical activity. The family environment has a significant impact on the development of eating behavior, so adults should provide a good model of this behavior for children. Conclusions: It was verified through this review that, in order to maintain and develop a healthy eating behavior, it is necessary to reach different spheres of life of the individual - physical, social, psychological, family, cultural and mediatic environment.

La comparación de las variaciones en el tiempo cronológico y en el espacio es uno de los aspectos menos estudiados en la ecología de las comunidades de parásitos. Por eso, en este estudio se compara la abundancia total, riqueza y composición de las infracomunidades de parásitos del róbalo Eleginops maclovinus (Cuvier & Valenciennes, 1830) (Pisces: Eleginopidae), entre muestras tomadas en Chile centro-sur en tres localidades geográficas (Talcahuano, Puerto Montt y Punta Arenas), y en dos momentos del tiempo en cada una de ellas. En el conjunto de las 126 infracomunidades examinadas se encontraron 18 taxa de parásitos. La abundancia total y la composición de las infracomunidades se modificaban con la ontogenia del hospedador. Sin embargo, se encontró que la variación entre años en una localidad es de similar magnitud a la que hay entre lugares geográficos, luego de corregir por el efecto de la ontogenia del hospedador. Estos resultados resaltan la necesidad de implementar diseños de muestreo más rigurosos al momento de usar a los parásitos como marcadores biológicos de las poblaciones de hospedadores. Se propone que futuros estudios en las fuentes de variación de las comunidades de parásitos mejoren la descripción de estas variaciones con diseños de muestreo con medidas replicadas en el tiempo y el espacio.Comparison of variations in both chronological time and space is one of the least studied subjects in the ecology of parasite communities. Thus, we compared the abundance, richness and composition of parasite infracommunities in the rock cod Eleginops maclovinus (Cuvier & Valenncienes, 1830) (Pisces: Eleginopidae), between three widely separated localities along south-central Chile (Talcahuano, Puerto Montt and Punta Arenas), which were sampled in two different years each. Eighteen parasite taxa were taxonomically determined in the 126 hosts examined. Total abundance and infracommunity composition changed along host ontogeny. However, and beyond the effect of the host ontogeny, analyses of the variance revealed that community descriptors of rockcod parasites at a given place vary as much between years as between places at a similar time. These results reveal the need to use more rigorous sampling designs whenever parasites are going to be used as biological tags of host populations. They also highlight the importance of using time and space replicated sampling schemes.

Description
An account of the resource
La yuca es determinante para la seguridad alimentaria de cientos de millones de personas alrededor del mundo. A pesar de que el principal medio de propagación del cultivo es a través de semilla asexual por estacas (tallos maduros) se ha revelado una relativamente alta diversidad intraespecífica, principalmente en los sistemas de cultivo de manejo tradicional. En esta revisión se documentan algunos estudios realizados sobre la diversidad de la yuca, tanto por marcadores moleculares como morfológicos, centrándose en aquellos realizados en el Amazonas. También se exponen los principales factores que han determinado el aprovechamiento y conservación de esta diversidad, tales como la aparición espontánea de semillas de origen sexual, el sistema de chagras indígenas, la memoria biocultural y la facilidad de intercambio de semilla entre comunidades. Finalmente, se pone de manifiesto que en los sistemas de manejo tradicional la conservación y uso de la diversidad intraespecífica se constituye en un elemento prioritario que se ha perdido en los sistemas de cultivo a gran escala. En los sistemas de manejo tradicional existe un vínculo etnobotánico que pervive e invita a buscar prácticas alternativas que aseguran un mantenimiento de la diversidad, permitiendo una productividad eficiente e incluso se hace un mejor manejo para disminuir los riesgos de incidencia de algunas plagas y enfermedades.

Aproximación a la obra de una teóloga ecofeminista

Description
An account of the resource
Presentamos aquí un análisis detallado del libro de Rosemary Radford Ruether Gaia y Dios. Esta obra tiene una triple raíz: está escrita desde una perspectiva ecológica, teológica y feminista. Gaia y Dios aborda el problema ecológico a partir de una visión religiosa del mundo, particularmente la de las religiones y tradiciones monoteístas convergentes en el cristianismo. Estas religiones y tradiciones son: la religión hebrea y la filosofía griego-helénica, particularmente Platón y el gnosticismo. A todo ello hay que sumar la nueva ciencia en el siglo XVII. Esto representa la culminación del pensamiento occidental basado en la idea de un Ser Único Trascendental, Dios, creador de todas las cosas, que somete a su creatura más perfecta: el varón, al cual queda también sometida la mujer. Según esta visión, la Tierra y todo lo que existe está al servicio del hombre, y éste debe dominarla, explotarla y extraer de ella todas sus riquezas. Es esta visión patriarcal la que resulta profundamente destructora y depredadora para Gaia, la Tierra, que la autora propone recuperar a través de su propuesta de una teología ecofeminista.
